The effects of final forging temperatures on deformability and structure evolution of high purity aluminum during multi-directional forging process were investigated.The results showed that increasing the initial forging temperature is beneficial for controlling the sample shape in the initial forging passes.Recrystalization during the initial forging passes improves the deformability of the sample in the following low-temperature forging processes.An X-shape fine grain zone is formed in the sample due to the inhomogeneous deformation of multi-directional forging process.When the forging pass is 6, the final forging temperature has an important influence on the grain size in the fine grain zone.The grain size decreases from 302 μm to 60 μm with the final forging temperature decreasing from 310 ℃ to 65 ℃.

为研究粘贴钢板加固T型混凝土梁的受弯性能及影响因素,对8根不同钢板加固量、混凝土等级、配筋率和U型箍间距的T型混凝土梁进行试验研究.该加固方法能够很好的改善加固梁的受弯性能,裂缝和应变的发展均有所延缓,均表现为受拉钢筋及钢板屈服,受压区混凝土压碎的破坏形态.加固后的T型混凝土梁三个特征荷载均得到显著提高,其中增大钢板的加固量,三个特征荷载的提高幅值较大.U型箍间距增大未造成钢板锚固破坏,因此对特征
地震易损性分析是地震灾害分析的重要内容,可以比较全面地评价结构的抗震性能,因此,快速有效地获得结构的地震易损性非常重要.本文以一RC框架为对象,同时考虑结构材料和地震动的不确定性,以中心复合设计法建立试样样本对,用OpenSees软件建模并对样本进行非线性分析,建立了基于高维模型表达的结构近似模型,继而采用蒙特卡洛模拟得到结构易损性曲线;并且将结果与响应面法得到的易损性曲线进行比对.分析结果表明:
